to remove the water of crystallization. They arethen reduced to finepowder, and thoroughly mixed together after having added one pound ofstarch. This mixture is now added to six pounds of pure lard that isentirely free from water, and the whole is thoroughly mixed together.

Any combination of ingredients yielding by decomposition carbonic acid,or other gas suitable to raise bread, may be used with the lard in placeof the compound herein described.

Subject each separately to a gentle heat, suflicient The lard preparedin this way may be used for all the purposes for which yeast orbaking-powder and lard are used.

The lard in this compound protects the chemicals against dampness, andpreserves their qualities intact. The chemicals also act as apreservative for the lard, keeping it sweet and preventing it frombecoming rancid. v

When the compound is used in cooking it answers the double purpose oflard and baking-powder, as the bicarbonate of soda is decomposed, andthe carbonic-acid gas is liberated by the action of the acid when itbecomes moistened and heated in the article with which it isincorporated.

Having thus described my invention, I claim as new and desire to secureby Letters Patout-- A compound formed of alum, bicarbonate of soda,lard, starch, and tartaric acid, as described.
